NAME

6       waffle_feature_test_macros - Macros to control definitions exposed by
7       Waffle's headers

SYNOPSIS

10       WAFFLE_API_VERSION
11       WAFFLE_API_EXPERIMENTAL
12
13

DESCRIPTION

15       Waffle's feature test macros allow the programmer to control the
16       definitions that are exposed by Waffle's headers when a program is
17       compiled. Conversely, the macros allow the programmer to control which
18       Waffle features a program's source relies on.
19
20       In order to be effective, a feature test macro must be defined before
21       including any header files. This can be done either in the compilation
22       command (cc -DMACRO=value) or by defining the macro within the source
23       code before including any headers.
24
25   Specification of feature test macro requirements in manual pages
26       When a function requires that a feature test macro be defined, the
27       manual page docments it in the SYNOPSIS. When an enum or macro requires
28       that a feature test macro be defined, the manual page documents it
29       either in the SYNOPSIS or where the enum or macro first appears in the
30       page.
31
32   List of feature test macros
33       WAFFLE_API_VERSION (since waffle 1.3)
34           This macro controls the API version exposed by Waffle's headers.
35           The value ((major << 8) | minor) exposes the API of Waffle
36           major.minor. For example, the value 0x0103 exposes the API of
37           Waffle 1.3. If this macro is undefined, then the headers expose the
38           API of Waffle 1.2.
39
40       WAFFLE_API_EXPERIMENTAL
41           This macro exposes experimental features in Waffle's headers.
42           Experimental features may be altered or removed without notice and
43           do not belong to Waffle's stable API.
